Every computer and mobile device uses some form of software to perform a particular task. For the last decade or so, software were being released on the internet with proper version in order to keep track features and updates. So in case of new release a new package with version were used to be update on websites. These days many individual application has its own updater component which prompt user about latest updates and upgrades itself automatically. ITunes App Store, Windows 10 App Store and Google Play Store are also modern example of software repository.

What is a package?

A packages is a collection of pre-compiled binaries, configuration files together into a single archive file for easier portability and storage, or simply compress files to reduce size. Packages also contain metadata, such as the software’s name, a description of its purpose, a version number, and a list of dependencies necessary for the software to run properly.

Each Linux distribution have created their own package formats. Some of the most commonly used package formats include:

  • deb is used by Debian, Ubuntu, Linux Mint, and other distro’s based on Debian.
  • rpm is used by Red Hat, Fedora, SUSE.
  • tar.xz is used by Arch Linux.

What is a package manager?

package manager or package management system is a repository of software tools that perform the process of installing, updating, configuring, and uninstalling software on operating system without the need for manual installs and interaction in a very consistent manner. More importantly it resolve dependencies required to run those programs itself. If you are a user with Linux background there’s a good chance you’ve used package manager to install programs. Linux was first OS which started the practice of maintaining a centralized where users could find and install software followed by Mac OSX while Windows have Windows Installer but with a GUI rather than command line. Package managers generally serve several functions:

  • Searching for software
  • Installing software
  • Upgrading software
  • Uninstalling software
